2 . In school, we are told to drink water between classes. Our parents ask us to bring our water bottles to school and we’re reminded by experts that water is good for our skin and helps control our weight. But how much should we actually be drinking?

For many years, people have followed the advice of drinking eight glasses of water, eight times a day, known as the “8×8 rule”. According to Jessica Brown, this seems to have partly come from a misunderstanding of old advice that was published almost 80 years ago. In 1945, a study advised drinking one millilitre (毫升) of liquid for each calorie (卡路里) of food. This is about two litres of water a day, or eight glasses per person. But, Jessica says, the reality is that different people have different needs. Weight, age and activity level all play a role in how much water someone should drink.

Then do we need to control how much water we drink? It’s not that important, according to Dr. Stanley Goldfarb from the University of Pennsylvania. He says our bodies are good at telling us when we need water. When we are thirsty, it means our bodies need more water. Our kidneys (肾脏) help us keep the water we have, even before we feel thirsty.

There are, of course, benefits to drinking water. It helps our bodies stay at the right temperature. It helps us keep away bad things in our bodies. It helps us digest (消化) food. It protects our joints (关节).

So, next time you feel thirsty, reach for a glass of water. But don’t worry if you don’t drink exactly eight glasses a day. Your body knows what it needs.

Nutritional grade labels (营养等级标签) A, B, C, or D on packaging are used to mark the percentage of sugar (含糖量) and saturated fat (饱和脂肪) in the drinks. The labels are from A to D. The more sugar and saturated fat a drink has, the less healthy the drink is.

4 . For most of us, it takes a long time to learn how to make something tasty. But not for Remmi Smith, still a teenager, she’s already creating fantastic dishes. She’s also becoming well known for her Italian salad dressing, which is delicious. And with her knowledge of social media (媒体), she’s making sure that everyone knows she’s here!

Remmi, who was born in China, now lives in the USA. She is just 16. She has already starred in two shows on cooking and her book of healthy recipes (食谱) has recently come out. From the age of four, Remmi helped in the kitchen by preparing vegetables. By the age of seven, Remmi was a real food love r who could cook complete meals for her family. Remmi began making videos for fun. Her mother videoed her while she was cooking and put the videos online. A local TV station broadcast (播放) them. They then asked Remmi to create another show.

That show is mainly about Remmi’s interest, which is getting teenagers to take healthy eating seriously. She believes that when young people make their own food, they care more about what they eat. Remmi works with a company in the USA which shows her videos in school dining halls. About 3.5 million students watch her every day!

Remmi believes that young people can create a healthy meal for their family which doesn’t cost a lot. Her delicious recipes include vegetable paella and strawberry kebabs. In fact, strawberries, which are Remmi’s favorite food, appear in other recipes, including strawberry sandwich!

Her latest idea is a healthy-snack service. For a monthly subscription (订购), you receive snacks, which include fruit sticks and popcorn, and fun cooking activities that help you develop a healthy lifestyle.

5 . There are growing facts that fast food is one of the worst parts of modern life. Studies have shown that burgers and fried chicken can cause health problems.

However, fast food restaurants are still attractive. The most important reason is that their service is fast. Their staff are friendly and very smart-looking in their tidy and bright uniforms. Moreover, most fast food restaurants are near places that people often pass by. It is so easy to just grab a burger and eat on the way to work.

Fast food is often so conveniently packed that it will not cause a mess even if you stand and eat it. Fast food restaurants are also very clean. A lot of clever ads have made them the coolest places, but none of them has ever told and will never tell you that too much fast food is not good for your health.

Such attractive places are selling junk food! Isn’t it a pity? Is there a way to change the fast-food restaurants into special places where you get the best possible, healthy and fresh food? As people realize the health problems that fast food causes, it is quite likely that fast food restaurants may go out of date sooner or later.

Therefore, instead of saying no to fast food restaurants, a better idea may be to persuade them to change their men. If they could join healthy food together with their speed of service and delicious tastes, that will be the next best thing on Earth for people!

7 . Have you ever thought about what’s more important looking fashionable (时尚的) or feeling comfortable? You might have noticed many people choosing style over comfort and some even go to extremes (极端) to follow fashion. But we should remember: it’s more important to be healthy.

Some people believe that they need to be a cert in size to look good. So, they start extreme diets (日常饮食). They might note at meals or eat too little, which can make them feel sick. Is it a healthy way to live?

Also, many girls wear shoes with very high heels. They might think high heel make them look taller. But these shoes can actually hurt their feet and make it hard to walk comfortably, and it can increase risks of falls, Some even wear tight (紧的) clothes that make it hard to breathe. Should we put fashion over health?

Besides, some boys and girls spend much time and money changing their hair color. The material they use is usually harmful to their heath. To make their hair straight or curly, they also use tools that are hot enough to burn their hair. But using these tools too often can make the hair dry or even burnt. Is it really worth it to risk our health, spending so much time and money?

So, let’s rethink what’s really important. Is it fashion or our well-being? Clothes or hairstyles don’t tell us anything about a person’s character. Instead of spending much time choosing clothes, we could use that time to do fun things with friends. And instead of following extreme diets, let seat properly and exercise regularly. Remember, your worth is not decided by your appearance (外表), but by who you are as a person.
